摘要

The adsorption of vapors of marker substances, the main pollutants diffusing into air from polymeric household products, is studied. An array of eight quartz crystal microbalance (QCM) sensors is assembled; it ensures the minimum effect of water vapors on the results of microweighing, the maximum sensitivity to one or several classes of organic compounds, and the identification of phenol/formaldehyde and acetone in mixtures with the aim to estimate the level of emissions of phenol, formaldehyde, toluene, and acetone from polymeric household products. A classification of samples of nonfood polymers by the degree of hazard is proposed taking into account the total concentration of easily volatile organic compounds and the presence of phenol/formaldehyde and acetone. The accuracy of the detection of phenol emissions by polymers is confirmed by a standard spectrophotometry method. The use of the sensor array allowed the reduction of the cost and time of analysis and the obtaining of information on the concentrations of other easily volatiles in one measurement.
